Device for guiding and holding down of sheets on a sheet stack

Device for guiding and holding down of sheets supplied singly by a conveyor device along a conveying track to a sheet stack (15) formed in a storage container (11) having a front wall (12), said device comprising:

• a two-armed lever (18) pivotably mounted about a bearing point (17) located above said sheet conveying track,
• said two-armed lever (18) including a first arm (19) serving as a sheet holding-down arm, at an acute angle to the surface of said sheet stack (15), resting with its free end on said sheet stack (15), and a second arm (20) adjustably supporting a weight (22), said first and second arms (19 and 20) forming with one another an angle (.gamma.) enclosing said bearing point (17) such that the line of application of force of said weight (22) is above said beating point (17) and such that, depending on the distance (1) of said weight (22) from said bearing point (17) and on said angle (.delta.), the center of gravity (24) of said lever (18) is on a line (25) forming an angle (.delta.) with said first arm (19) to provide a predetermined hold-down force.
